Development of ytterbium-doped oxyfluoride glasses for laser cooling applications
Oxyfluoride glasses doped with 2, 5, 8, 12, 16 and 20 mol% of ytterbium (Yb(3+)) ions have been prepared by the conventional melt-quenching technique. Their optical, thermal and thermo-mechanical properties were characterized. Luminescence intensity at 1020 nm under laser excitation at 920 nm decreases with increasing Yb(3+) concentration, suggesting a decrease in the photoluminescence quantum ...
متن کاملLaser safety importance in clinical laser applications

متن کاملLaser based applications : Existing and Future Solutions
The IAEA continues to provide credible assurance to the international community regarding States’ adherences to their safeguards obligations under the nuclear NonProliferation Treaty. Generally, industrial activities, including those related to the nuclear fuel cycle, are operating on increasingly larger scales involving more equipment, more nuclear material products and flows. With limited res...
متن کاملLaser Cooling of Semiconductors
Optical irradiation accompanied by spontaneous anti-Stokes emission can lead to cooling of matter, a phenomenon known as laser cooling or optical refrigeration proposed in 1929 by Peter Pringsheim. In solid state materials, the cooling is achieved by annihilation of lattice vibrations (i.e., phonons). Since the first experimental demonstration in rare-earth doped glasses, considerable progress ...
متن کاملLaser cooling of atoms
The concept of radiation-pressure cooling of atoms was independently suggested in 1975 for the case of a gas of neutral atoms by Hänsch and Schawlow, and for atomic ions bound in an electromagnetic trap by Wineland and Dehmelt. While the notion that momentum exchange from a photon moving in the opposite direction could slow an individual atom was well understood, until this time no one had come...
